"He wrote, abridged, revised, and published a library of fifty volumes known as the 'Christian Library,' and some time after he re-read, revised, corrected, and published the whole in thirty large volumes. This library contains one of the richest collections found in the English language.
"He wrote a good-sized work on electricity.
"He prepared and published for the common people three works on medicine.
"He published six volumes of church music. His poetical works, in connection with his brother Charles, amounted to not less than forty volumes. Charles wrote most of them, but they passed under the keen revision of John, without which we doubt if Charles Wesley's hymns would have been what they are—the most beautiful and soul-inspiring to be found in the English language.
"In addition to these multiplied publications, we have seven large volumes, including sermons, journals, letters and controversial papers known as 'Wesley's Works.' It is claimed that Mr. Wesley's works, including abridgments and translations, amounted to at least two hundred volumes. It is difficult to understand how a man could have found time to accomplish so much literary labor while perpetually on the wing.
"In addition to all this, Wesley was a pastor and did more real pastoral work than nine-tenths of the pastors of these times. One has only to read his journals to be convinced of this. For a time he visited all the class and band meetings, and had special charge of the select societies. He appointed all the class and band leaders, stationed all the preachers, and had a general oversight of the many thousands of his followers.
"He improved every moment of the day. Mr. Fletcher, who was for some time his traveling companion, says of him, 'His diligence is matchless. Though oppressed with the weight of seventy years, and the care of 30,000 souls, he shamed still, by his unabating zeal and immense labors, all the young ministers of England, perhaps, of Christendom. He has frequently blown the gospel trumpet and rode twenty miles before most of the professors who despise his labors have left their downy pillows. As he begins the day, the week, so he concludes them, still intent upon extensive service for the glory of the Redeemer and the good of souls.
"'From four o'clock in the morning until ten at night every moment was occupied in loving efforts to save the lost; and he never lost ten minutes from wakefulness at night, as he himself affirmed. His motto was, "always in haste, but never in a hurry." "Leisure and I have taken leave of each other." "Ten thousand cares are no more to me than ten thousand hairs on my head." "I am never weary with writing, preaching or traveling," are a few of the utterances of this remarkable man. And in the midst of all this wonderful activity he says, "I enjoy more hours of private retirement than any man in England."'"
No wonder he could shout on his dying bed with the heavenly halo around his head and say, "The best of all is, God is with us."
Look at that apostle of faith, George Muller, after he had prayed in millions of dollars, cared for thousands of orphans, preached in many lands and sent missionaries throughout the world, still active for God between eighty and ninety years of age.
